Hypertext: an Educational Experiment in English and Computer Science at Brown University is a documentary film from 1976 made by Brown University computer scientist Andries "Andy" van Dam.
The film was funded by a 1974 grant provided by the National Endowment for the Humanities to support "an experimental program to teach a college-level English poetry course, utilizing a new form of computer based 'manuscript,' called a hypertext." More information about the grant is available on the NEH website. To read the story behind how this film was re-discovered in 2016, see this article on the NEH website.

The Hypertext system used in the film is called FRESS and was developed by Andy van Dam, Carol Chomsky, Richard Harrington, and others based on the hypertext idea developed by Theodor Nelson.
The Hypertext poetry class described in the film was conducted by Jim Catano, Carol Chomsky, Nancy Comley, and Robert Scholes.
Film production was done by Michael Silverman, Bill Gallery, and Peter O'Neill.
